Sri Lanka is one of the Asian countries most affected by mosquito-borne diseases, especially malaria. This 18-month study assessed the effectiveness of a new community-based ecosystem management programme to control mosquito vectors in the country's rice ecosystem. Farmers in a malaria-prone village were educated and motivated to engage in source reduction as well as measures to restore and maximise rice ecosystem functions. Over the course of the programme, the impact of farmers' ecosystem management on local mosquito ecology was also examined. Although little impact was detected on Culex and Aedes densities, adult Anopheles density was significantly suppressed in the southwest monsoon season. Rice farmers who manage their ecosystems can reduce the burden of Anopheles mosquitoes, interrupt malaria transmission and prevent the destruction of ecosystems.
斯里兰卡是受蚊媒疾病影响最严重的亚洲国家之一，尤其是疟疾。这项为期18个月的研究评估了一项新的基于社区的生态系统管理计划在该国水稻生态系统中控制蚊媒的有效性。对一个疟疾高发村庄的农民进行了教育并激励他们采取减少源头以及恢复和最大化水稻生态系统功能的措施。在该计划实施过程中，还研究了农民生态系统管理对当地蚊虫生态的影响。虽然未检测到对库蚊和伊蚊密度有显著影响，但在西南季风季节，成年按蚊密度显著降低。管理其生态系统的稻农可以减轻按蚊的负担，中断疟疾传播并防止生态系统遭到破坏。
